Fix kewordgen to generate current Keywords.cpp with minimal diff,
but also to be compatible with old usage and kwgen files.
Add new parameters:
%no-namespace-for-tokens - not use namespace for tokens
%pre-check-argument - set type and name of additional variable to use
%function-name - name of a function ("classify" by default)
%pre-check - name of a variable to check for a keyword (i.e. cxxEnabled)
Now "%%" is also used to end and restart keywords parsing to be able to
generate additional keywords for classifyOperator()
Automatically add checks for LanguageFeatures to generated code
Pass input and output files with command line arguments, print usage
Update Keywords.kwgen to include all keywords currently used
Add missing aliases to Token.h
